Weather theories

With reference to JD Mangan’s letter (Jun 24) there is a difference between weather and climate change.

Frustrating as it is, Ireland is an island in western Europe, off the Atlantic Ocean. Therefore, our climate is dictated by the weather systems that circulate in this region. This means average temperatures throughout the year, resulting in gentle winter months and slight cooler summer months. To prove climate change requires long-range forecasting over hundreds of years. Such forecasting models need to consider parameters such as hours of sunshine, levels of rainfall, daily temperatures and precipitation.
